沛（pei）
Name meaning
沛 (pei) means abundant water, vigorous flow and generous force. In naming it usually reads as full-bodied energy arriving in a broad stream.
Practical naming use
沛 (pei) is an abundance-and-momentum character. It gives a name force, generosity and water-borne energy, so the result feels strong without turning harsh. It is especially useful for cultural depth, classical reference, personality image, because the character can carry a recognizable Chinese image without becoming empty dictionary filler. The best results come when the second character adds human direction, warmth, restraint or breadth, so the full given name feels lived-in rather than generic.
Pair 沛 (pei) with characters such as 泽 (ze) for beneficent flow, 安 (an) for controlled force, 文 (wen) for cultured vitality or 明 (ming) for bright energy. The second character should shape the surge into a person.
沛然 (Peiran): Pei contributes abundant water, vigorous; Ran adds natural, so.
